Hi,
I got a fresh git clone running here.
Yet, the PostgreSQL backend doesn't work.
Regardless of whether I'm attempting to convert an SQLite database to PostgreSQL or try to initialize one, PostgreSQL query errors are reported:

I followed the howto on the wiki, permissions are set correctly. As you can see, connection and interaction to / with PostgreSQL is working fine.
